Background: Patients receiving cytotoxic therapy for solid tumours are at risk of severe influenza. However, few data are available regarding the immunogenical efficacy of influenza vaccine in these patients.
Methods: In this prospective study, 25 patients with breast (n=13) or prostate (n=12) cancer received a trivalent inactivated influenza vaccine along with docetaxel (Taxotere) administration. The influenza virus type A and B antibody titres were measured using haemagglutinin inhibition (Garten et al, 2009) before and 21 days after the vaccination. Seroconversion rate was defined as the percentage of patients with an increase in the serum titres ≥ 4 after vaccination.
Results: Median age was 65 years (range: 33-87 years); 52% were females. Seroconversion rates were low: 28% (95% CI: 23.1-33.3) for H1N1, 8% (95% CI: 7.7-8.3) for H3N2 and 16% (95% CI: 7.7-25) for the B strain. The geometric mean titres ratios were 2.16 (H1N1), 1.3 (H3N2) and 1.58 (B). No serious adverse event (AE) related to the vaccine was reported. All the reported AE were from mild-to-moderate intensity.
Conclusion: In the patients receiving docetaxel for solid tumours, influenza vaccine triggers an immune response in only one third. Strategies using more immunogenic influenza vaccines must be evaluated in such patients.

Background: Infections by and influenza viruses are vaccine-preventable diseases causing great morbidity and mortality. We evaluated pneumococcal and influenza vaccination practices during pre-international travel health consultations.
Methods: We evaluated data on pretravel visits over a 10-year period (1 July 2012 through 31 June 2022) from 31 sites in Global TravEpiNet (GTEN), a consortium of US healthcare facilities providing pretravel health consultations.

Generating effective live vaccines from intact viruses remains challenging owing to considerations of safety and immunogenicity. Approaches that can be applied in a systematic manner are needed. Here we created a library of live attenuated influenza vaccines by using diverse cellular E3 ubiquitin ligases to generate proteolysis-targeting (PROTAR) influenza A viruses.

Manipulating viral protein stability using the cellular ubiquitin-proteasome system (UPS) represents a promising approach for developing live-attenuated vaccines. The first-generation proteolysis-targeting (PROTAR) vaccine had limitations, as it incorporates proteasome-targeting degrons (PTDs) at only the terminal ends of viral proteins, potentially restricting its broad application. Here we developed the next-generation PROTAR vaccine approach, referred to as PROTAR 2.

Multiple sclerosis (MS) is a severe autoimmune disorder that wreaks havoc on the central nervous system, leading to a spectrum of motor and cognitive impairments. There is no cure, and current treatment strategies rely on broad immunosuppression, leaving patients vulnerable to infections. To address this problem, our approach aims to induce antigen-specific tolerance, a much-needed shift in MS therapy.

From influenza to COVID-19, emerging infectious diseases have taken a heavy toll on lives and resources. Emerging infectious diseases represent one of the largest threats to national security. The primary mission of the Center for Biomedical Advanced Research and Development Authority (BARDA), within the US Administration for Strategic Preparedness and Response, is to support the advanced development of medical countermeasures (MCMs) for public health security threats, including select infectious diseases.
